A primer on the three types of barcode: the traditional 1D linear code, the 2D data matrix, and the QR code powered by GS1 Digital Link — and why the new one changes things.
GS1 Sunrise 2027
A supplier's guide to QR codes powered by GS1
You know the barcode is changing. This guide explains what GS1 Sunrise 2027 and Tesco's Project Sunrise actually mean on your production line, and how to tell if you're ready.
The change
What is GS1 Sunrise 2027, and what's actually changing?
The barcode is being upgraded. Led by GS1's global Sunrise 2027 initiative, retailers are moving from the traditional linear barcode to 2D barcodes: QR codes powered by GS1 Digital Link, which can be read at the checkout as well as by shoppers. Tesco is among the first UK retailers trialling them on selected own-brand lines.
Unlike today's barcode, a single GS1 Digital Link QR code can carry much more. It holds the GTIN, plus data like batch number and use-by date, and links the physical pack to online content. Tesco's early trials focus on capturing use-by dates and batch numbers at the till, which helps reduce food waste and prevents expired products being sold.
The wider goal, Sunrise 2027, is the industry ambition for retailers to be able to scan these 2D barcodes at point of sale by the end of 2027. It's currently trials and clear industry direction rather than a blanket mandate, but the direction of travel is set, and suppliers who prepare early will be in a far stronger position.
The case for change
Why does it matter, and what do 2D barcodes actually deliver?
For retailers and shoppers, 2D barcodes unlock far more product information at the checkout and beyond. The benefits driving adoption are clear.
40%
Less food waste
Up to a 40% reduction, as achieved by Woolworths in Australia using GS1-powered 2D barcodes.
Fewer expired sales
Checkouts can read the use-by date held in the code and stop out-of-date products being sold.
Stronger traceability
Confirm product authenticity and surface ingredient and origin detail, building consumer trust.
Better inventory management
Supports first-in-first-out, improves availability and reduces waste further.
These are the reasons the industry is moving. The harder question, and where most suppliers need clarity, is how to produce these codes correctly on a live production line. That's what the rest of this guide covers.
The reality on the line
Where do suppliers get caught out?
The most common assumption is that this is an artwork change: new code on the pack, job done. In practice it reaches into your data, your printing, your verification and your line systems, and that's usually where projects stall.
- 1
Getting the code structure right
A GS1 Digital Link QR code can look perfect and still be wrong. If the underlying structure isn't built correctly, it may not scan reliably or work with retailers' systems down the line.
- 2
Hitting the print quality standard
Tesco's guidance for fresh products sets a minimum grade of B. A QR code holds far more data than a linear barcode, so contrast, substrate, print resolution and placement all affect whether it grades and scans.
- 3
Verifying every pack
Printing the code isn't the finish line. You need to confirm the right code, carrying the right data, printed to the right quality, on every pack, with a record to prove it.
- 4
Making the systems talk to each other
Codes depend on printers, cameras, line software and product data working together. The technology is rarely the hard part; keeping accurate data flowing across all of it is.
- 5
Proving it after the fact
When a code fails or an audit comes knocking, you need a defensible record of what was printed, when, and how the quality was checked.
Most suppliers underestimate at least one of these. The fastest way to see where you stand is a short readiness check.
Two-minute check
How ready are you for GS1 QR codes?
Before you plan a pilot, it helps to know where you stand today. This quick check takes about two minutes and covers the areas that trip suppliers up most. You'll get an instant picture of where you're in good shape and where the gaps are.

The steps to getting QR-ready
A practical walkthrough of the journey from “we've been asked to do this” to printing verified codes on your line.
What your solution needs to do
A closer look at the four things every QR setup has to get right on the line.
Short on time?
Every QR solution comes down to four steps
Manage
Keep control of your product data, so the right data goes into every code.
Generate
Build the code to the GS1 Digital Link standard: the Tesco URL, then GTIN, batch number and expiry date, each in the correct format.
Print it inline as the date code is applied. Your substrate, printer type and line speed all shape what's possible, and it usually needs white space adding to the artwork.
Verify
Check every pack for the right data and good enough print quality to beep at the till, with a record kept for audit.
The single best first move? Print some samples early and get them checked. You won't get it right first time, and finding that out now beats finding out at rollout.

How OAL helps suppliers get QR-ready
OAL helps food manufacturers make this work on real production lines, from a first check of whether your line can handle it, through to verifying live codes and keeping the evidence for audit.
Technology readiness assessment
We look at your line, printers and software and tell you honestly what can print and verify QR codes as-is, and what would need to change.
Sample checking
Print a few codes and send them over. We'll confirm the GS1 Digital Link structure is right and that the print grades well enough to scan at the till.
Getting the line working together
Practical help joining up your data, printing and verification so the right code, with the right data, prints on every pack.
Verification and audit evidence
In-line checks on every pack, with a full digital record you can stand behind in a BRC or retailer audit.
OAL Connected is certified by GS1 UK to create, print, verify and manage GS1 Digital Link QR codes, so this isn't theory. It's already running in factories.
Proof
Why leading food manufacturers trust OAL
“Without a doubt I would recommend OAL to other manufacturers […] this system is the failsafe.”
“I've been very impressed with the OAL system, it's really been a game-changer for us. What was originally brought in to prevent product recalls has now become an invaluable tool to improve our production efficiency.”
